Prentiss, Inc., Sumter, South Carolina s. c.-, assignor in my 8. 0., a corporationfot Application June 14, 1937, Serial no, 14am 7 Claims. (o1. 112-79) My invention relates to tufting machines. An important object 'of the invention is to provide a machine of the above mentioned character, which is extremely simple in construction, compact, and reliable'in' operation. 7

A further object-of the invention is'to pro-- vide means whereby the looper and cutter may be readily removed asa unit. 7

. A further object of the invention. is to provide 103 means whereby the looper' is moved by the cutter. I A further object'of the invention is to provide means to operate the cutter, which means is independent of the work feed means;

Other objects and advantages of the invention will be apparent during ,the course of the follow-' ing description. I

Inthe drawings wherein for the purpose of iilustration is shown a preferred; embodiment of myinvention, the numeral i0 designates a sewing machine as a whole, of any well known or preferred type, such as the-ordinary Singer sewing machine, I comprising a stock ll, arm l2 and head l3. The stock is mounted upon a flat base H. The head I3 is provided with the usual vertical reciprc awry needle bar IS-having a needle l6 clamped thereto. This needle has the usual eye at its lower pointed end for receiving the tufting yarn or thread, passed through the usualguide and tension means, not shown.

The machine comprises the usual drive shaft 25, of the same,

I'l, suitably journaled in the arm l2, and horizontally arranged-,2 as. shown,v and driven by v a grooved pulley l8, which maybe manually or power driven.v At its forward end the drive shaft ll isprovided with a crank disc i9 rigidly secured -theret0,; and having pivotal connection with a link 20. This linkis-pivotally connected with a sleeve 2l, 'which is clamped tothe'needle bar Ii. The machine further comprises a presser i'oot 22, of the usualconstruction-clamped to a presser bar 23, moveddownwardly by the'usual spring and raised by a finger engaging lever.

Arranged-below the. base M are horizontal rock shafts 25and 26,-which are'held in suitable bearings, The sewing; machine furthercomprises work feed means, to advance the work from the operatoninciuding work feed dogs 21 operating through a suitable opening in the base or through the throatplate, as, is well known. These dogs are actuated .by'a rigid dog support ing bar or link 28, to which theyare rigidly secured. At one end,,the bar or link is rigidly connected with a transverse headila, which v is piv- ,otally connected with upstanding cranks 30, in turn' rigidly mounteduponthe rockshaft'ZE.

.. ,Ati ts opposite end the rigid bar or link,28 is provided with a fork 31, receiving a roller32, pivotally'mounted upon a mama; in turn rigidly mounted upon the rockshait 26. The rock shafts therefore serve as' th 'fi dpei'atingv means for'the bar-28, serving-1 f {actuate the work feed means. Theserock shafts extend longitudinally of the drive shaft l1. and are parallel therewith. The rock shafts and 26 are provided adjacent to the stock H with cranks (Hand 'respcctively. The cranks 34 and 35 are pivotally connected with connecting rods 36 and' 31 respectively, whichare actuated by cams 38 and39 respec tively, in turn carried and driven by the drive. shaft l1. It might be stated at this point that the rock shaft 25 serves to move the dog carrying bar or link 28 longitudinally, while the rock shaft 25 serves to raise and lower the same.

The rock shaft I1 is also provided with a crank 49. The foregoing description is that of the erdinary Singer sewing machine. I, T

Depending from the base i4 arelugs 4| and-42, within which is mounted an. auxiliary rock shaft liyarrang'ed between the rock shafts 25 and 26, and parallel therewith. Rigidiy connected'with the rear end of the rock shaft 43 is'a crank 44, having a block 45 pivotally connected'therewith, and sliding in an elongated slot 4'6 of a bell crank lever 41.- 'This bell crank lever is carried by: a

I needle rises, and as the needle approaches or and the cutting edge It moves from the looper element as the looperelement moves toward the needle to provide, a suitable space for the.loop when thelooper element enters the loop.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred;example of the same out departing from the spirit of my invention or the scope of the subioined claims.
